Abstract
A bending method utilizes a die including a V-groove at an upper part thereof, and a punch including a first surface and a second surface at a workpiece pressing portion. In a state of being mounted on an upper table of a press brake, the first surface is parallel to a first groove wall surface of the die mounted on a lower table. An angle formed between the second surface and a perpendicular plane is different from an angle formed between a second groove wall surface and the perpendicular plane. A plate-shaped workpiece placed on the die is bent in a state of being sandwiched between the first groove wall surface and the first surface.
